CORN-PLANTER CHECK-ROWER.

SPECIFICATION fanning part of Letters Patent No. 315,220, dated April 7,1885.

Application filed- February 9, 1883. (Modem Be it known that We, ALDENBARNES and MONROE BARNES, citizens of the United States, residingatBloomington, in the county of Mc Lean and State of Illinois, haveinvented certainnew and useful Improvements in Corn- PlanterGheck-Rowers; and we do hereby declare the following to be a full,clear,andexact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to corn-planter checkrowers of that class inwhich a tappet-wire stretched over the ground to be planted is used as ameans for actuating the seed-slides through the instrumentality of aforked lever with which the tappets on the wire come in contact; and theinvention relates especially to that subdivision of this class ofcheck-rowers in which the forked lever swings in a horizontal plane. Theinvention consists, first, in improved 5 means of transmitting motionfrom the forked lever to the seed-slides of the planter; second, in anovel manner of arresting the motion of the drive-wheel; third, in anew-combination of the guide pulleys for the tappet wire;

fourth, in a novel means for doffingor releasing the "wire fromthecheck-rower; and, further, in constructions and combinations here-'inafter described. 7 v

In the accompanying drawings, which illustrate our invention,and inwhich the similar letters used as marks of reference apply to the likeparts III all of the figures Figure l is atop plan of the check-rowdevice. and the forward part of an ordinary corn-planter on' which it islocated for operation. Fig; '2 is an enlarged top plan of part of thecheck-rower. Fig. 3is aside elevation. Fig. at is a rear elevation. Fig.5 is a plan of the crank-bar for operating the swinging pu1leys. Fig. 6is a side elevation of one of the links connecting the forked leverswith the pawls. Fig. 7 is a side elevation of the drive-pinionand itsactuating-pawls.

. Referring to the drawings by letters, A represents the forward part ofan ordinary cornplanter, and B the sliding bar, which connects and movesthe seed slides in any ordinary manner.

O is the ordinary bar which carries the check-row devices. The bar 0 maybe fixed to the seed-boxes of the planter, as shown, or otherwise, asrequired.

To each end of the bar 0 a plate, D, is fixed, each of which carrysimilar devices, only one set of which need be described here- 1n.

E is an elbow-shaped forked lever, pivotally connected at its bend b tothe plate D or the bar G, as may be desired, so that it may swing inahorizontal plane in an ordinary manner.

F F are grooved guide-pulleys journaled on is planting, they rotate inor about in hori zontal planes, and while in said normal posi tions arelocated so. that the flanges f of the pulleys F F project beyond thecylindrical part of the pulleys H H, as shown by full lines at Fig; A,and thereby retain the tappet-, wire between the pulleysH H and the pulleys F F, as shown by the full lines at same figure. The pulleys H H areplain cylinders with a flange,c', on the upper end of each, which flangemay be dispensed with. The levers I I are journaled at z" 1',respectively, to standards J J, which project upwardly from the outerends of the plate D. The inner end of each lever I I has a slot, i,whichreceive, respectively,the crank ends is of a rockshaft, K. The innerends of the levels I I are shown as-bent downward somewhat, in orderthat the rock-shaft may be located beneath the bar 0. These levers maybe used straight by locating the shaft Kabovethe bar 0. I v

To one of the cranks k, preferably the one in the rear as relates to theplanter, an arm, is fixed, from which a cord, 1", or any other suitabledevice, extends to within reach of the driver in his seat on theplanter, and by means of which, when the planter reaches the ends of therows, he may turn the shaft K, so that the cranks It will swingthelevers I I, as shown by dotted lines at Fig. 4, and thereby releasesthe tappet-wire, so that it will fall clear of the planter, which maythen be turned round to commence the next bout without the driverdismounting to remove said wire. In coinmencing the new bout the driverplaces the tappet-wire to the pulleys F F, and then turns the rock-shaftK to swing the levers and to bring the pulleys H H into position toretain the wire, as hereinbefore described.

L is a drive-pinion journaled on a stud, Z, which projects from the barD, and provided on its upper side with aseries of ratchet-teeth or lugs,Z. Each tooth Z has a vertical side, Z, and a sloping top side, Z.

M M are'pawls, each loosely fitted at one end on the stud Z, so that itmay swing or oscillate horizontally thereon, and also so that theirouter parts may rise slightly to pass over the teeth Z. A link, N,connects one pawl M with the inner end of the forked lever, which is atone end of the bar 0, and a similar link N connects the other pawl Mwith the forked lever at the other end of the bar 0, as shown at Fig.

V in gear with the pinion L.

Q is a link connecting a crank-pin, 19, on the pinion 1? with theordinary lever B, which lever extends downward and hasa pin, 1, on itslower end that rests in a slotted standard, 7", which is connected withthe bar B.

As the planter moves forward in operation each tappet gswings the outerend of the forked lever rearward in the direction of the arrow shown atFig. 2, and the spring 8 returns said lever to its normal position andready for the action of the next tappet in the ordinary manner. As'theouter end of the forked lever swings rearward its inner end, by means ofthe link N, connected therewith, will swing the pawl M,connected to saidlink, and the pawl M, engaging with the vert-ical side Z of aratchettooth, Z, will give a partial rotation to the drive-pinion L, asshown by dotted lines at Fig. 2. The movement of the pinion L lastdescribed is arrested at the proper time by means of the detent a comingin contact with one of the cogs of said pinion, as shown by dotted linesat same figure. Each movement of the pinion L as last described gives ahalfrotation to the pinion P, and thereby through the link Q and lever Ba throw to the bar B and seed-slides of the planter. Each movement ofthe pinion P is terminated with the crank-pin p on its dead-center,thereby forming a lock in the ordinary manner to pre vent accidentalmovement of the seed-slides. WVhen the spring 8 returns the forked leverto its normal position, the pawl M will be swung backward thereby, andwill slide up the sloping side of one of the ratchet-teeth Z, andfalling behind said tooth will be ready for action on its vertical sideat the next movement of the forked lever. WVhen the forked lever at oneside of the planter and its connected link N and pawl M are moving thepinion L, the forked lever at the other side of the planter and itsconnected link N and pawl M will remainstationary, thus saving theuseless and, in some respects, injurious movements of these parts whennot required.

1. Th'e combinatiomwith a check-row wire and with forked levers adaptedto be oscillated thereby, of push bars or rods connected with saidlevers and a central revolving plate or wheel connected with theseed-slide, and provided with a series of projections whereby anintermittent rotary motion is given to the central wheel by either rod,substantially as and for the purpose specified.
